Özet:

This study was carried out to determine the effects on the dehydrogenase enzyme of steel coal compost, waste compost and tobacco processing waste applications on the soil with different pH values in greenhouse conditions. Examples of land used in the study were taken from the land and surface (0-20 cm) located in the Samsun Bay and around it. Soil samples have thin, medium thin and medium texture, acid, neutral and alkaline pH values, low salt content, low and medium organic content, low and high scratch content. According to the split-divided test pattern, the study applied steel coating compost, waste compost and tobacco processing waste to the soil in two repetitive doses (%0,%2.5,%5 and%7.5) in four different doses. The plant was grown in the prepared environment after a month of incubation period. According to the analysis and evaluation results, the application of steel coal compost, waste compost and tobacco processing waste to acidic (Tepecik), neutral (Campus) and alkaline (Chetinkaya) soils increased dehydrogenase activity. Tobacco processing waste is found to be more effective in acid-reactive topic soil, while waste compost is found to be more effective in alkaline-reactive Chetinkaya soil. The activity of dehydrogenase has been observed to increase with increased application doses in acid soil, while in alkaline and neutral soil it has been observed to decrease with increased application doses. The effectiveness of the regulators applied to the soil has come to the conclusion that the regulators are varied depending on the doses and characteristics of the application, and also the soil is acidic, neutral or alkaline.
